even the appraisal methods for CVCV and VCVC.coms are quite off the mark, IMO. Frankly, other than super premium CVCV.coms (Hobo.com, Gobo.com etc.), you can't pick out one name and say that the name will get a minimum of xx dollars. Sales have been amazingly fluctuating.
I remember zToy.com going for low x,xxx on Snap a month back. So yes, meaningful names + letters are worth something quite a bit more than non meaningful LLLL.coms
Good luck with it!
